PROJECT TITLE :

Nonlinear relaxational polarization in aluminum oxide

ABSTRACT:

Frequency and electrical field dependent measurements of the advanced capacitance on Al2O3 based metal-insulator-metal capacitors were conducted. A nonlinear relaxational polarization in Al2O3 was investigated systematically by suggests that of varying the thickness of the dielectric and characterizing samples at various temperatures. Using the uneven double well potential model, where the charges fluctuate between two potential minima, we tend to show that the relaxational polarization in metal oxide can be interpreted.
